....Dieselman743, huwyngr, Phil_D, Snowbunnie, Floating_Red, Stu and TechOutsider for the help and advice they gave me on this thread
I finally installed NIS 2009 a couple of days ago and it seems to be working well. I used the NRT to uninstall my previous version of NIS first. No doubt I'll be back both to solve any problems that may occur and learn more about the program.
Thanks again to all of you, have a great weekend!
